The following factors can be used to convert from

English to the most common SI Metric values.

TEMPERATURE

To convert degrees Fahrenheit (°F) to degrees Celsius

(°C), subtract 32° and multiply by 5/9 or 0.5556.
Example: (45.0 °F - 32°) x 0.5556 = 7.22 °C
To convert a temperature range (i.e., a range of 10.0 °F)

from Fahrenheit to Celsius, multiply by 5/9 or 0.5556.
Example: 10.0 °F range x 0.5556 = 5.6 °C range
